If you are using a concave slide, it may not be possible to focus on some things at the bottom of the concavity. I have a 47.5x that has an adjustment collar for different coverslip thicknesses, and even then the useful range is still give or take a tenth of a millimeter Ohhh, I see, that's cool! I...

To add to what 75RR said, as magnification goes up the working distance tends to go down. With higher power objectives it's possible to have media that's too thick to view all the way to the bottom of the specimen. I have some slides of ticks which are troublesome with the 100x oil as the specimen ...

. In general, the higher the magnification the closer to the cover slip the objective tends to be. Always work up to the maximum magnification, i.e. start with your 4x (good to scan the cover slip and get an overall of view of things), then move up to 10x, then the 20x if you have one, followed by ...

So I was trying the use the 40x objective and it would only show white... But then it worked after I moved the coarse focusing. The objective is literally touching the coverslip though, is that normal? Are objectives usually supposed to touch the coverslips? With 4x and 10x I didn't need to touch th...

InstantMochiii,
Congratulations on ordering your scope! The decision process over, time to enjoy the hobby.
Have you collected any water samples yet?

Not yet, but I hope to be able to very soon!

I made a Discord server for microscopy. I didn't know where to post this. I thought it'd be cool to be able to talk in real-time over chat with people who also like microscopy! https://discord.gg/p2DwTsgN Also... If you want to be a moderator, go to the announcements channel. Because I kinda need so...

Ok, so I ordered my microscope and the slides and coverslips and now I'm confused. I heard I had to clean the coverslips and slides before use even if it's pre-cleaned so I took them all out but then there was this paper thingy in between each of the slides and surrounding the coverslips. Like the ...

. Not all slides and cover slips need cleaning out of the box, that is only necessary if they come quite dirty. If they look clean i.e. not foggy, then you are good to go. Put them back in the box! If you are going to reuse the slides and or cover slips then see link bellow. https://www.microbehunt...

I have never owned my own microscope before, however my fondest memories of my labs in my undergrad was whenever we would drag those bad boys out. I got quite comfortable with using the models they provided (not sure which models exactly) but while I understand the parts of a microscope and how to ...

Thank you for replying everyone! Hehe~

So I'm probably being annoying with all these questions, but what is the CPC cap thingy on the T490B? https://youtu.be/oGHTM8-SfTc?t=473 Is that just a dust cap? Also, how is the light split between the trinocular port and the ocular port? Can you control it? Edit: I just realized that I've posted 2...

I just got finished ordering my 1st scope, T490A-DK. I am so looking forward to it’s arrival. Also ordered polarization film (linear), phone adapter, extra ep’s for said adapter, pipettes, tweezer set, blank slides/slips, the book:”Ponds and small lakes” and a 60X Plan objective ( I know some folks...

I live in Korea south. I started to play with microscope recently, only hobby. I am happy to find this forum because this forum can be very very helpful for me. I hope to make micro world around me into beautiful scenery. But I realized that it is very hard work and was deeply frustrated. My broken...

Hello everyone, I'm a college biology student and a lifelong science enthusiast. I had a toy microscope growing up and had some limited experience with real microscopes in high school and college. A while ago, I caught the microscopy virus afresh and I got the stronger strain this time. My fellow b...

You may have tipped the scales, Louise. Besides the wattage issue, I can’t get an answer from Amscope about the “400” series. The “490” is such a success why take a chance? I can’t wait to be observing and not dithering about what scope to get ! I’m hoping to find a stentor or hydra ASAP. I think t...

I guess I could buy T400A-30W, go right to the 100X-oil and look for vibration. That’s a hard way to get an answer. First: I don’t plan use the 100-oil at all, or rarely. Second: If it did vibrate and I was dissatisfied there is the hassle of returning one scope while waiting for a new one to arriv...

Will I vacillate yet again? Stay tuned!!

The fact that I related to this so much hurts- lol

In all honesty, I don't know either... I feel like the T490 is pretty good, and I don't know what level of control you would need for the halogen bulb. Then again, it's pretty bright, has 'daylight' light, and easily replaceable, the only con is that it heats up. But then, the LED is not as bright (...

Great Questions! There is a frosted portion inside the removable black piece whose thread diameter I was discussing (the collector lens). I will take some more complete pictures of the LED assembly. It is difficult because there is a wire or two that prevents me from opening the LED access door ver...

XDDD Thank you for always helping me out, haha~! I'm thinking T490 is probably what I'll go for now, hahaha. 👉👈 One last question would you say that it's easy to replace the bulb on your halogen microscope? I have no experience (like at all, except for changing the battery in my TV remote) with cir...

Even though I have the halogen version... The T490 is the same albeit different lighting, Here are the answers. Yes 95% mostly. The xy knobs could be sturdier and the condenser up and down knob could be sturdier. Otherwise all good. You'l treat er' like it's your baby anyway yes yes yes yes yes yes...

Ok, never mind now, lol~ The product page is working again~!

GwBF-jElTBQ I am a beginner. Sorry I could't make subtitles in English as it needs too much time for me. But someday I can make subtitles in English. The name of the lives may not be correct. I have bought a very thick book recently, 'PROTISTS OF KOREA(an illustrated protozoan book).' Ha~ useless~ ...

Ok, I see XD Thank you ScienceMatters and Greg!

Ok, so I'm thinking of this microscope, so I have a few questions... 1) Where did you get the phase contrast turret kit? Is it compatible with the T490? 2) Does the halogen work ok and not kill sensitive organisms? I heard that halogen can do that, and so I'm thinking to get the LED version, but th...

So, after a *lot* of research, I've mayyyybe decided on an Amscope T490B-LED. The only problem is, when I go to Amazon, the product description is basically non-existent, and when I go to the website, it doesn't show for some reason? Like, I'll search it up, but when I go to the product page all I s...

3W should be sufficient for regular brightfield, but may be insufficient when using filters that block a lot of light or when using light intense methods such as darkfield. Are there any microscopes with an LED light that is 30W? T-T Or is that hard to do with LED? :( To be honest, wattage doesn't ...

Is the only difference between an Amscope T490B and an Amscope T490B-DK that the T490B-DK comes with a darkfield condenser and the T490B doesn't?

Here is my microscopes and everything thus far I have purchased from Amscope. Only really posting because there doesn't seem to be a lot of knowledge out there on Amscope products which makes people not trusting of Amscope. Like when I finished college and graduated from my fish and wildlife techni...
